New Studies Presented at European Society of Anaesthesia Further Validate Masimo PVI(TM) for Noninvasive and Continuous Fluid ...( IRVINE Calif. June 12 /- Masimo (Nasd...),Health

IRVINE, Calif., June 12 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry(TM) and Measure-Through Motion and Low-Perfusion pulse oximetry, announced today that three new independent studies demonstrating the clinical accuracy and utility of Masimo PVI as a noninvasive and continuous measure of patient fluid status and responsiveness were presented this week at the European Society of Anaesthesiology (ESA) Annual Congress in Milan, Italy.

Although fluid administration is critical to optimizing patient status and enabling end organ preservation, unnecessary fluid administration is associated with increased morbidity and mortality. Traditional invasive measurements such as central venous pressure are not reliable to predict whether a patient will benefit from fluid administration, and newer more reliable methods to predict fluid responsiveness are also invasive and costly. Multiple recent studies have shown that Masimo PVI provides a simple and cost-effective method for accurate, noninvasive, and continuous monitoring of fluid responsiveness. The three studies presented at the ESA reinforce the accuracy of PVI compared to invasive measures and highlight its value for before, during, and after anesthesia.

Does the Pleth Variability Index correlate with stroke volume variation? Researchers in the Department of Anesthesiology at the Hamamatsu University School of Medicine in Hamamatsu-City, Japan, compared the accuracy of Masimo PVI measurements with Stroke Volume Variation (SVV) obtained via an invasive catheter (Flo Trac(R)) in 13 patients. After analyzing data recorded at five points--in the supine position, lateral position, start and end of one-lung ventilation, and in the supine position again--researchers found a significant correlation between PVI and SVV (r = 0.75; p = 0.02).
